Description

(54) STAND FOR 1SPNOGO TRANSPORTER ASSEMBLY

one

The invention relates to mechanical assembly work, in particular to devices for assembling and riveting the chain conveyors of combine harvesters.

A device is known for assembling and casting chain-type products, chain conveyors containing a riveting mechanism mounted on a bed and a feed mechanism made in the form of an additional chain conveyor and carriage, with parallel rollers with sprockets mounted on them and connected to a piston of a power cylinder. through the lever and the stop mounted on the tlJ bed

However, the known device does not provide, j cakes the required performance and quality of assembly, as it has a complex structure, and also does not ensure the assembly of conveyors from two chains.

The chain of the invention is to provide improved build quality and productivity.

This goal is achieved by the fact that a stand for assembling a chain conveyor, a socializing mechanism for riveting mounted on the frame, and a mechanism for feeding the chain conveyor into the assembly zone, made in the form of a carriage connected to the power cylinder and mounted on one of the parallel shafts, This shaft is located on the carriage, and the other shaft is made full of leading gear, equipped with an overrunning clutch with an eccentric mounted on the drive shaft, and adjustable along the length of the slide with a groove hinged to the frame, while the eccentric of the coupling laid in the groove backstage.

In addition, the carriage is mounted for movement in a vertical plane.

FIG. 1 shows a stand, general view; in fig. 2 - feed mechanism.

Claims (2)

The stand consists of a mechanism for claws mounted on frame 1, made in the form of hydraulic cylinders 2, each of which has a piston 3 fixed on the piston rod. Located in guide sleeves 4, 395 feet 5 are mounted on the frame with dies 6 fixed on it and pins 7. On the base 1, a chain conveyor feed mechanism is also mounted in the assembly zone, made in the form of a movable carriage 8 mounted in guides 9 and connected with the rod of the power cylinder 1O. On the carriage 8, there is a leading shaft 11 and a shaft 12 parallel to it with sprockets 13 fixed on it. On the drive shaft 11 there is an overrunning clutch 14 with an eccentric 15; On the base 1 it is also hingedly fixed on the bracket 16 and is adjustable in length by means of a tension nut 17 is a slide 18 with a groove in which the eccentric 15 of the overrunning clutch 14 is located. The stand operates as follows. The conveyor chains to be assembled are put on the sprockets 13 of the movable carriage 8, and chain links with riveting holes are fixed by pins 7 on the table 5. The rivets are set by the heads in the spherical grooves of the dies 6. Then the links with the holes and are riveted on the rivets. planks are applied. A hydraulic distributor lever (not shown) turns on the mechanism for the film and padrock cylinders 2 provide movement of the punches 3 in the guide sleeves 4. This forms the locking heads of the rivets. After the riveting of the strips to the conveyor chain, the conveyor is moved a distance corresponding to the step of the conveyor strips. From the control valve, the power cylinder 10 is turned on, which lifts the carriage 8 together with the chains laid on it, withdraws the chain links with riveted strips from the engagement with the locking pins 7. At the same time, the eccentric 15 of the freewheel 14 is moved into the slot of the wings 18 and reaches the end of the slot. Upon further upward movement of the carriage 8, the overrunning clutch 14 is rotated by a certain angle corresponding to the linear movement of the chains by the step of the slats. The magnitude of the adjustment of the pitch of the conveyor is provided by adjusting the length of the backstage 18 with the taut nut 17 and the magnitude of the stroke of the power cylinder rod 10-14. Then the reverse stroke is engaged. Before the carriage 8 stops the eccentric 15 reaches the lower end of the groove of the scenes 18 and with further movement of the rod of the power cylinder 1O down, the overrunning clutch 14 excludes linear movement of the chains backwards and the conveyor chains moved to the stride step, are lowered onto the table 5 of the stand. In this case, the links with holes for rivets sit on the pins 7. Thus, the carriage 8 returns to its original position and the cycle repeats. The proposed stand, compared with the device taken as a prototype, makes it possible to automate.nifeifecc assembly of conveyors of combine harvesters SK-6 and reduce assembly time of one conveyor by 1.3 times and, thus, improve assembly quality and productivity. Claim 1. A stand for assembling a chain conveyor comprising a riveting mechanism mounted on a frame and a chain conveyor feeding mechanism into the assembly zone made in the form of a carriage and sprockets attached to the power cylinder and mounted on one of two parallel shafts, the shafts being located on the carriage, and the other shaft is made leading, characterized in that, in order to improve the quality of assembly and productivity, it is equipped with an overrunning clutch with an eccentric mounted on the drive shaft and adjustable in length to street with a groove hinged to the frame, with the eccentric coupling located in the groove backstage. 2. The stand according to claim 1, of which the carriage is mounted so that it can move in a vertical plane. Sources of information that are cared for in the examination 1.
